Hello! Adding a line item along with an associated subscription line item to cart via API seems to be failing after upgrading solidus to 3.4, solidus_subscriptions to 2.0 and solidus_stripe to 5.0. Our API request is as follows:

POST /orders/${_orderNumber_}/line_items

Request body:

{
  "line_item": {
    "quantity": 1,
    "variant_id": 60
  },
  "subscription_line_item": {
    "quantity": 1,
    "interval_length": "4",
    "interval_units": "week",
    "subscribable_id": 60
  }
}

Response:

{
  "status": 500,
  "error": "Internal Server Error"
}

Stack Trace (from GCP logs):
